I stayed for 2 months and the stay was good. I had no issues. WIndy responded to messages quickly. The apartment was clean, and checkin and checkout were easy.
The apartment is a bit far from the BTS, and the shuttle only runs hourly to the station, and only for part of the day, no shuttle from the station. But there are many inexpensive motorcycle and car taxis to take if you need them.
I would recommend the apartment.
